Block Diagram
Description
Pericom Semiconductor’s PI4ULS3V16M is a 16-bit (dual-octal)
non-inverting bus transceiver with two separate supply rails.
A port (VCCA) and B port (VCCB) are set to operate at 1.4V to
3.6V. This arrangement permits universal bidirectional translation
of differential signal levels over the voltage ranges.
PI4ULS3V16M is designed for asynchronous communication
between data buses. Data is transmitted from the A bus to the B
bus, or vice versa, without direction control. All AX, and BX are
tri-stated when data is coming from both directions at the same
time. The output-enable (OE) input is used to disable outputs so
buses are isolated.
The control pins, SEL, TEST_EN and Out_SEL are supplied by
VCCB.
The device is fully specified for partial power-down applications
using IOFF. The IOFF circuitry disables the outputs, preventing
damaging current backflow through the device when it is powered
down.
To ensure the high-impedance state during power-up or power-
down, the output-enable (OE) input should be tied to VCC through
a pullup resistor.
